Bethe Ansatz Solutions to Quasi Exactly Solvable Difference Equations
Symmetry, Integrability and Geometry: Methods and Applications, 2009 Bethe ansatz formulation is presented for several explicit examples of quasi exactly solvable difference equations of one degree of freedom which are introduced recently by one of the present authors.

International Journal of Mathematics and Mathematical Sciences, 2006 We show that if v is a symmetric regular Laguerre-Hahn linear form (functional), then the linear form u defined by u=−λx−2v+δ0 is also regular and symmetric Laguerre-Hahn linear form for every complex λ except for a discrete set of numbers depending ...

Simplifying large spin bootstrap in Mellin space
Journal of High Energy Physics, 2018 We set up the conventional conformal bootstrap equations in Mellin space and analyse the anomalous dimensions and OPE coefficients of large spin double trace operators.

Journal of Biogeography, EarlyView.ABSTRACT Aim How communities of organisms come together has long fascinated scientists, with renewed interest in using functional and evolutionary patterns to infer mechanisms of community assembly. Ecological theory predicts that biotic interactions could lead to either divergence in the event of niche partitioning or convergence through the exclusion

Phenomic Prediction Can Be Improved by Optimization of NIRS Preprocessing
Plant Breeding, EarlyView.ABSTRACT In recent years, phenomic prediction has emerged as a new method in plant breeding that has been shown to have great potential. However, there are still many open questions regarding its practical application. For example, in the field of spectroscopy, it is standard practice to optimize the preprocessing of spectra, which so far has only been

On 2-orthogonal polynomials of Laguerre type
International Journal of Mathematics and Mathematical Sciences, 1999 Let {Pn}n≥0 be a sequence of 2-orthogonal monic polynomials relative to linear functionals ω0 and ω1 (see Definition 1.1). Now, let {Qn}n≥0 be the sequence of polynomials defined by Qn:=(n+1)−1P′n+1,n≥0.

Laguerre–Hahn orthogonal polynomials on the real line [PDF]
Random Matrices: Theory and Applications, 2019 A survey is given on sequences of orthogonal polynomials related to Stieltjes functions satisfying a Riccati type differential equation with polynomial coefficients — the so-called Laguerre–Hahn class. The main goal is to describe analytical aspects, focusing on differential equations for those orthogonal polynomials, difference and differential ...

The effect of result‐based agri‐environmental payments on biodiversity: Evidence from Switzerland
American Journal of Agricultural Economics, Volume 107, Issue 4, Page 1228-1254, August 2025.Abstract We estimate the effects of result‐based agri‐environmental payments on biodiversity using a unique dataset containing information about plant vegetation. The data include information on surveyed plant species for a large number of randomly selected plots followed over a period of 20 years in Switzerland.

How Should We Treat Farmed Animals? Adolescents Are More Speciesist Than Adults
Social Development, Volume 34, Issue 3, August 2025.ABSTRACT Adults engage in psychological processes (including species‐based categorisation and post‐hoc reasoning) that result in ascribing high moral value to some animals while eating others. Do adolescents engage in similar processes? We compared adolescents’ (n = 89, M age = 13.54) and adults’ (n = 113, M age = 43.73) views on four measurements ...

The Fractional Orthogonal Derivative
Mathematics, 2015 This paper builds on the notion of the so-called orthogonal derivative, where an n-th order derivative is approximated by an integral involving an orthogonal polynomial of degree n.
